어떤 이유로 GO (진행) 버튼을 클릭하면 MainScreenHandler가 두 번 반복됩니다. 첫 번째 클릭에는 발생하지 않지만 후속 클릭에는 발생합니다.한 번의 클릭으로 여러 번 반복되는 동작 수신기
첫 번째 클릭 후 액션 수신기를 ChoiceHandler로 변경 한 다음 MainScreenHandler로 다시 변경하기 때문에 문제가 있다고 생각합니다.
나는 이것이 왜 있는지 전혀 모른다.
저는 Java를 처음 사용하고 GUI로 모험 게임을 작성하려고합니다. 다른 팁도 감상 할 수 있습니다.
다음은 MainGameScreen 클래스입니다.

의견에 감사드립니다. 나는 액션 리스너를 올바르게 제거하고 있다고 생각했지만 그렇지 않다고 생각한다. 사용자가 두 번째 선택을해야하는 경우 새 버튼으로 새 화면을 만들려고 시도합니다 (예 : GO, DIRECTION). – stevo78
